OOLLAPSIBLE BOX.

Specification of Letters Patent.

Patented May 4, 1920.

Application filed April 1, 1918. Serial No. 226,041.

To all whom it may concern:

Be it known that LCALvIN F. GHnis'roriinn, a citizen of the United States, residing at Canton, in the county of Haywood and State of North Carolina, have invented a new and useful Collapsible Box, of whichthe following is a specification.

The subject of the present invention is a collapsible box, and the invention contemplates the provision of a collapsible box for pianos or organs, though the same may be used in the construction of boxes designed for other purposes.

A main object of the invention is the provision of means for securing the-parts of the box together.

A further object of the invention is the provision of means for attaching the parts of the box to the bottom.

The invention also contemplates adjustable braces for .the back of the box.

A still further object within the contemplation of the invention is to generally iniprove the construction andv enhance the utility of collapsible boxes.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combinationand arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope ofwhat is claimed without departing from the spirit of the invention.

A practical embodiment of the invention is shown in the accompanying drawings, wherein Figure 1 is a view in side elevation of a box constructed in accordance with the invention;

Fig. 2 is a rear elevation of the same, a portion being broken away;

Fig. 3 is a longitudinal section on the line 3-3 of Fig. 1;

Fig. 4c is a cross section on the line 44 of Fig. 2;

Fig. 5 is a detail sectional view taken on the line 5-5 of Fig. 2.

Referring to the drawings by numerals of reference:--

In carrying out the invention there is provided a bottom 10, formed of wood or other suitable material, and around the periphery of the bottom are secured, by nailing'or otherwise, the upper and lower cleats 1.1. The edge of the bottom is mortised to provide thespaced recesses 12 about the periphery of the bottom.

Secured to the bottom thus formed, are a back 13; a front 14; and two sides 15, to the bottomedges of which are secured by screws or otherwise the angled lugs 16, the inturned ends of which are adapted to enter the recesses 12 and bind the bottom to the back, front, and ends or sides.

The front let is surmounted by the usual sloping portion 1%, and the box has a top 19 which rests on the upper edge of the portion 14 and the upper edge of the back 13.

The sides 15 project beyond the back 13, front 1 1, sloping portion 14 and top 19, and these projecting edges have spaced apertures through which pass the binding bolts or rods 17, which are adapted to bind the sides firmly in place by any suitable means such as the wing nuts 18 which are threaded on the ends of the bolts or rods 17.

The bolts or rods 17 extending along the back of the box pass through longitudinally spaced, transverse slots 20, formed in braces 21 which rest against the outer face of the back 13. The braces 21 are also provided with longitudinal slots 22 which register with horizontally disposed slots 23 formed in the back 13. The braces may be clamped in adjusted positions by bolts or like elements passed through the slots 22 and 23.

it is desired to store the same or return it to the factory or house from which the piano or the like was shipped.

Owing to the presence of the slots 23, the bolts 50 may be shifted in the back 13 longitudinally of the rods 17, thus permitting the inner ends of the bolts to clear parts of the piano within the box. The same adjustment permits the braces 21 to be shifted transversely so as to reinforce the back 18 if the same is checked at its ends, or happens to be knotty, punky or checked at points spaced inwardly from its ends. There is an advantage arising out of the fact that the braces 21 may be adjusted endwise. Because an endwise adjustment is possible, the back 13 may be reinforced, adjacent to its top or adjacent to its bottom, if the back, at its top or at its bottom, is made up of relatively narrow boards, the endwise movement of the braces 521 permitting the braces to extend across the crack between the top board of the back and the next lower board, or across the crack between the lowermost board and the next upper board.

Having thus described the invention, what is claimed as new and sought by Letters Patent, is 1- l. A box comprising a first wall; second walls at the ends of the first wall and pro jecting beyond the first wall; rods connecting the projecting portions of the second walls; braces cooperating with the first wall and having openings elongated longitudinally of the braces and receiving the rods, the braces and the first wall having rectan gularly disposed elongated slots; securing devices in the slots; and other walls cooperating with the walls specified, to complete the box.

2. A box comprising a first wall; second walls at the ends of the first wall and projecting beyond the first wall; rods connecting the projecting portions of the second walls; braces cooperating with the first wall and having openings receiving the rods; means for securing the braces to the first wall at adjusted points along the first wall longitudinally of the rods; and other walls cooperating with the walls specified, to complete the box.

3. A box comprising 'a first wall; second walls at the ends of the first wall and projecting beyond the first wall; rods connecting the projecting portions of the second walls; braces cooperating with the first wall having openings receiving the rods and elongated longitudinally of the braces; and means for securing the braces to the first wall at adjusted points longitudinally of the braces along the first wall; and other walls cooperating with the walls specified, to complete the box.

a. A box comprising a first wall; second walls at the ends of the first wall and projecting beyond the first wall; rods connecting the projecting portions of the second walls; braces cooperating with the first wall and having openings receiving the rods and elongated longitudinally of the braces; means for securing the braces to the first wall at adjusted points along the first wall, longitudinally of the braces and longitudinally of the rods; and other walls cooperating with the walls specified, to complete the box.

5. A box comprising a bottom having a recess in its edge; a cleat secured to the lower surface of the bottom and extended across the recess; a cleat secured to the upper surface of the bottom and extended across the recess; a wall supported on the last specified cleat; an angle member mounted on the wall and including a part extended into the recess and received between the cleats; and other walls cooperating with the bottom and with said wall to complete the box.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature inthe presence of two witnesses.
